How to Make Flat Iron Steak
-
Preheat your grill or cast-iron skillet to medium-high heat. This ensures a perfect sear, locking in all the flavor and juices to create that mouthwatering crust we love.
-
Whisk together the marinade in a bowl by combining olive oil, Worcestershire sauce, lemon juice, garlic powder, fresh herbs, salt, and pepper. This aromatic blend will infuse your steak with delicious flavor.
-
Marinate the flat iron steak by placing it in a resealable bag or dish and pouring the marinade over it. Let it spend at least 30 minutes in the fridge to absorb all the savory goodness.
-
Rest the steak for about 15 minutes after removing it from the marinade. This step is crucial for even cooking, allowing the meat to come closer to room temperature.
-
Sear the steak on each side for about 4-6 minutes, aiming for that appealing medium-rare doneness (around 130°F). Look for a beautiful golden-brown crust to form while cooking!
-
Rest the steak for at least five minutes before slicing it against the grain into thin strips. This resting period helps the juices redistribute for a tender and juicy bite.

Flat Iron Steak Recipe FAQs
What’s the best way to choose ripe ingredients for my flat iron steak marinade?
Absolutely! For the freshest flavors, select bright and fragrant herbs—preferably organic, if available. Look for fresh lemons that have smooth, shiny skin and give slightly when you press them. This indicates ripeness and juiciness. For olive oil, choose a cold-pressed, high-quality extra virgin variety to elevate your dish.
How do I store leftover flat iron steak?
To keep leftover flat iron steak fresh, store it in an airtight container in the fridge for up to 3 days. Make sure it has cooled completely before sealing it to maintain its delicious flavor. If you’d like to extend its shelf life, you can also freeze the cooked steak!
Can I freeze leftover flat iron steak? If so, how?
Absolutely! To freeze your leftover flat iron steak, first let it cool completely. Then, wrap it tightly in plastic wrap, ensuring no air is trapped inside. Place it in a freezer-safe bag and remove as much air as possible before sealing. It can be stored in the freezer for up to 3 months. Remember to label it with the date for easy reference!
What if my steak is tough after cooking?
Very! If you find that your steak is tough, it may be due to not slicing it against the grain. Slicing with the grain can lead to chewier bites. Additionally, ensuring that you do not overcook the steak—keeping it at approximately 130°F for medium-rare—is crucial. If your steak was overcooked, remember to let it rest properly next time to maintain tenderness.
Are there any dietary considerations I should be aware of?
Definitely! If you’re cooking for guests, be mindful of common food allergies. For instance, Worcestershire sauce contains anchovies, which can be a concern for fish allergies. If cooking for kids or pets, ensure the seasonings are mild and avoid any garlic powder or onion powder, as they can be harmful to dogs and cats.
How long can I leave the marinated steak in the fridge?
While it’s important to let your flat iron steak marinate for at least 30 minutes, I recommend not exceeding 24 hours for best results. Longer marination can lead to a mushy texture due to the acidic ingredients like lemon juice. For that perfect balance of flavor without compromising the meat’s integrity, 30 minutes to 24 hours is ideal!
